New research using coral records indicates that climate change is intensifying El Niño events. Scientists analyzed centuries-old coral samples from the Pacific Ocean to reconstruct historical El Niño patterns. The data shows a clear trend of stronger and more frequent El Niño episodes in recent decades, linked to rising global temperatures.

This strengthening could lead to more extreme weather worldwide, including droughts, floods, and storms. The findings highlight the growing impact of human-driven climate change on natural climate cycles. Experts warn that continued warming may push El Niño beyond historical variability, increasing risks for vulnerable regions.

The study underscores the urgency of climate mitigation efforts to stabilize global weather systems.
